What Social Download All In One does and who it is for

Social Download All In One abstracts the complexity of scraping or reverse-engineering social media platforms by giving you a single endpoint that accepts a URL and returns ready-to-use download links. Instead of maintaining separate parsers for each platform, you submit any supported social media link and get back structured metadata alongside direct media URLs categorized as video, audio, image, or other.

This fits several developer profiles: builders of browser extensions or desktop apps that let users save media locally; backend services that archive social content for moderation or research; or mobile apps that need a lightweight, ready-made extraction layer without hosting their own scraping infrastructure.

The recorded average success rate is 100% and the average response latency sits at 1,484 ms. That latency figure is worth keeping in mind — it reflects real-world extraction time from third-party platforms, so it is not suitable for synchronous UI flows where you need sub-second responses. Background jobs or async queuing are the natural fit.

The single endpoint and response shape

The entire API surface is one endpoint:

POST /v1/social/autolink

You send it a social media URL and the API resolves the platform, fetches media metadata, and returns a unified JSON object. Every response follows this schema:

{
  "url": "",
  "source": "",
  "author": "",
  "title": "",
  "thumbnail": "",
  "duration": "",
  "medias": [
    {
      "url": "",
      "quality": "",
      "extension": "",
      "type": ""
    }
  ]
}

A few fields deserve closer attention:

  • source — identifies the originating platform, which means you can branch your UI logic based on what came back rather than parsing the input URL yourself.
  • medias array — a single post can yield multiple entries. A video post might return an MP4 at multiple quality levels, a separate MP3 audio track, and a thumbnail image, all in one response.
  • type — values are video, image, audio, or other, letting you filter by media kind without inspecting file extensions.
  • extension — reflects the actual container format (e.g., mp4, mp3, jpg), so you can label or route files correctly on the receiving end.
  • duration — populated for video and audio; useful for displaying length before a user initiates a download.

Because there is only one endpoint, integration is minimal: authenticate with your RapidAPI key, construct a POST request with the target URL, and parse the response.

Pricing breakdown

The API uses a tiered freemium model. Overage billing applies on PRO, ULTRA, and MEGA when the monthly quota is exceeded.

Plan Monthly cost Requests / month Rate limit Overage per request
BASIC $0 100 — —
PRO $2 6,000 3 / second $0.0030
ULTRA $5 22,000 4 / second $0.0010
MEGA $10 60,000 5 / second $0.0010

The BASIC tier's 100 requests per month is enough for personal experimentation or a prototype demo, but will be exhausted quickly in any real application. At that volume — roughly three requests a day — it is best treated as an evaluation tier.

PRO at $2/month gives 6,000 requests, which equates to about 200 per day. At a $0.003 overage rate, exceeding the quota gets expensive proportionally; if you consistently go over, stepping up to ULTRA makes financial sense. ULTRA and MEGA share the same $0.001 overage rate, so the cost of an unexpected traffic spike is much more manageable at those plans.

MEGA, the recommended tier, offers 60,000 requests per month — 2,000 per day at a flat $10 — with the highest included rate limit of 5 requests per second. For a small production service or a moderately active tool, MEGA likely covers you without frequent overage charges.

Practical use cases

Media archive tools. Teams that monitor brand mentions across social media often need to preserve original media alongside metadata. The author, title, and thumbnail fields provide enough context to catalog content meaningfully without additional API calls.

Download manager apps. Desktop or mobile apps that let users paste a social URL and retrieve the best-quality file can rely on the quality and extension fields to build a download picker. Multiple entries in the medias array mean you can offer format and resolution choices with minimal extra work.

Content repurposing pipelines. Creators who cross-post content across platforms sometimes need to retrieve original assets from one platform to upload to another. The unified response structure means the same code path works regardless of the source.

Academic or journalistic research. Researchers preserving public social media content for analysis can batch-process URLs. At the MEGA tier, 60,000 requests per month supports moderate-scale data collection.

Limitations and things to check before integrating

Latency. At an average of 1,484 ms per request, blocking a user interaction on this call will feel slow. Design your integration around this: queue requests asynchronously and return results when ready rather than waiting inline.

Platform coverage. The API is described as supporting all major social media platforms, but the documentation does not enumerate which specific platforms are included. Before building on it, test with the exact platforms you need to support. The source field in the response can help you validate coverage programmatically.

Rate limits on BASIC. The free plan has no documented per-second rate limit listed, but the very low monthly cap (100 requests) is the binding constraint in practice.

URL-dependent extensions. Per the documentation, the extension field depends on the format of the original link — meaning you may occasionally see less common containers. Ensure your downstream code handles formats beyond the common MP4/MP3/JPG set gracefully.

No batch endpoint. Each request processes a single URL. If you need to process many links simultaneously, you will need to manage concurrency on your side while respecting the plan's per-second rate limit.

Getting started

The API is available through RapidAPI under the name Social Download All In One. Sign up for the BASIC plan at no cost, grab your RapidAPI key, and make a POST request to /v1/social/autolink with a social media URL in the request body. The response structure is consistent across platforms, so a single integration handles all supported sources.

For custom arrangements or volume pricing outside the standard plans, the provider offers an alternative endpoint at zm.io.vn and can be reached at [email protected]. The provider also lists a separate elite plan on RapidAPI (download-all-in-one-elite) for higher-volume needs beyond the standard MEGA tier.
